Stolen....

Oops, I gave link to Oregon Cameras; you're in Washington State - here is that link

Also, I looked at Google Street view of 348th and 9th and I think I am seeing two video cameras on the traffic signal poles at that intersection - one pointing straight at the entrance to the park and ride, and one pointing up 348th.

I know there are devices that trigger the signal for emergency vehicles - but I think those are smaller - these really do look like cameras but maybe somebody here knows..
